Rob Kardashian is showing once again just how much he respects women -- by slut shaming his ex on Twitter some more. Klassy!

Kardoucheian took to the microblogging site once again to attack singer Rita Ora, but then hid behind the transparent veil of anonymity he draped over her identity.

In yet another flurry of since deleted tweets (preserved via Radar Online), Kardashian attacked an apparent posting from Ora.

The original post read, "Rob's d--- was wack, I had to go get it somewhere else." Rob replied, "So you let me get you pregnant and you let others hit raw?" That sound you just heard was a million girls reaching for birth control pills and gagging.

Here's the problem: Ora never posted the tweet. The screencap from which it was derived included a photo Ora hasn't used for her Twitter avatar in quite a while and was written differently from her typical bubbly style.

When Kardashian came under fire for throwing his ex under the bus, he responded like a really brave soul ... on Twitter. Again. In more tweets that he later erased, Kardashian wrote, "Just so we clear I never once mentioned 'Rita Ora' in any of my tweets or even used the word 'whore' and I never would. I Respect Women ... Sad that the media created negativity for a young artist new to the game that is working so hard to make it. Never mentioned any names."

Okay, but you're not denying it -- and you're pointing out again that whichever ex cheated on you is just starting to get her career going.

Something tells us it's a good thing this guy didn't go into his father's field. If he can't keep his stories straight in terms of social media, who knows what would happen if someone found a bloody glove at his best bro's place?
